A network node may identify a single first packet size associated with a plurality of packets. The network node may transmit the plurality of packets to a UE based on a MIRS. Each packet in the plurality of packets may be associated with the single first packet size. The UE may decode the plurality of packets based on the MIRS. Each packet in the plurality of packets may include a first number of systematic bits and a second number of parity bits. The first number of systematic bits may be associated with a first cyclic buffer at the network node. The second number of parity bits may be associated with a second cyclic buffer at the network node.

Methods, systems, and devices for wireless communications are described. The described techniques provide for a transmitting device and a receiving device to coordinate channel aware tone reservation (CATR) control information using distributed coding. The transmitting device and receiving device may estimate a similar wireless channel and select a set of reserved tone locations and may each independently encode the set of reserved tone locations. In some cases, the receiving device may receive parity information associated with the set of reserved tone locations selected by the transmitting device and may jointly decode the parity information with the set of reserved tone locations predicted by the receiving device to detect and correct one or more errors in the predicted set of reserved tone locations.

Certain aspects of the present disclosure provide techniques for digital pre-distortion (DPD). An apparatus for wireless communication generally includes a power amplifier (PA); a first DPD circuit, a second DPD circuit, and a transmitter. The first DPD circuit is generally configured to: obtain an input signal; apply a first DPD to the input signal to generate a first resulting signal; and output the first resulting signal to the second DPD circuit. The second DPD circuit is generally configured to: obtain the first resulting signal from the first DPD circuit; apply a second DPD to the first resulting signal to generate a second resulting signal; and output the second resulting signal to the PA. The PA is generally configured to amplify the second resulting signal to generate an amplified second resulting signal. The transmitter is generally configured to transmit the amplified second resulting signal to a second apparatus.

Digital pre-distortion and assistance information signaling

Aspects are provided including one or more techniques for graphics processing involving hierarchical modulation and foveated rendering. A first wireless device obtains, from a network entity, a hierarchical modulated image including higher and lower priority bits. The first wireless device also obtains gaze information from a second wireless device indicating an associated foveal region. In response to the gaze information, the first wireless device processes a portion of the hierarchical modulated image associated with the lower priority bits using the gaze information. For example, the device decodes low priority bits in the hierarchical modulated image in regions closer to the fovea. The first wireless device subsequently provides an image including the processed portion to be rendered at the second wireless device. For example, the processed image may have a higher resolution in the regions closer to the fovea but a lower resolution in regions farther from the fovea.

Methods, systems, and devices for wireless communication are described. A user equipment (UE) may receive an indication that the UE is to apply a digital-post distortion (DPoD) procedure to a received signal to reduce non-linearities of the received signal. In some examples, the UE may determine one or more autocorrelation values for a power delay profile (PDP) of a channel, receive an indication of a matrix, and identify coefficients (e.g., b-coefficients) for use in the DPoD procedure based on multiplying the autocorrelation values and the matrix. Alternatively, a network entity may determine the autocorrelation values indicate them to the UE for use in identifying the coefficients. In some other cases, the network entity may use the autocorrelation values and the matrix to determine the coefficients and then may indicate the coefficients to the UE. The UE may apply the DPoD procedure to the received signal using the coefficients.

Calculating coefficients in low-complexity digital post-distortion procedures

Methods, systems, and devices for wireless communication are described. A transmitter device may encode information for a message using a spinal code. The transmitter device may divide the information into sets of bits each including a variable quantity k of bits, and map the sets of bits to symbols to generate a message. The transmitter device may transmit the symbols in an order based on the k values (symbols with smaller k values at the beginning of the message and larger k values at the end). Based on receiving the message, a receiver device may identify the k of each symbol and decode the symbols. The receiver device may identify a partial codeword or determine a likelihood of error associated with the message, which the receiver device may indicate via a feedback message. The transmitter device may retransmit a portion of the message based on the feedback.
